Add three new shell tools that bypass shell escaping issues by using
subprocess with list arguments instead of shell interpretation:
- curl: HTTP client with proper JSON body handling
- jq: JSON processor with direct filter passing
- wget: File/site downloads with mirror mode support
These tools solve the common problem of shell escaping nightmares
when working with complex JSON or special characters.
Updates:
- Added CurlTool, JqTool, WgetTool to hanzo-tools-shell
- Updated __all__ exports and TOOLS list
- Added tools to entrypoint_loader PACKAGE_TOOL_PREFIXES
